In xml Invoice Standard v2.2, Line#231'AddOnChargeName', under the column of 'SIS-Cargo Category Billing', says ' Should be one of the following values: ISCAllowed/ISCAccepted/ISCDifference
If we put 'AddOnChargeName'='AmountSubjectToISCAllowed', then which line will show the actual amount?
Take a CC AWB for example, if the route is A---B---C---D, and is carried respectively by airline X, Y, Z. Weight Charges for A-B is GBP8; B-C is GBP12 and C-D is GBP13. If X bills Y in xml format, how does carrier X to show these information such as AmountSubjectToISCAllowed=GBP25; ISC=5%; ISC amount=1.25.
Could you please give us an example of XML especially the values of Line#231 to 235 in this case?
